What should you do if your monitor keeps turning off on Windows 10? This problem can be quite bothersome, but luckily, it can be resolved with ease. Below are some troubleshooting steps provided by MiniTool to help you resolve the issue effectively.

Monitor Keeps Turning Off

While using a computer, various software or hardware problems might arise, causing the device to act unpredictably, such as the monitor issue. Specifically, your computer is powered on, yet Windows isn't loading, and there's no signal on the monitor screen, or a message indicates that the monitor is entering sleep mode. Alternatively, you're using your computer normally when the screen unexpectedly turns black.

This could stem from a connectivity issue, a system file malfunction, a power plan setting, an outdated driver, among other reasons. How can you prevent your monitor from going into sleep mode in Windows 10? You can address this issue with the following troubleshooting solutions.

Solutions to Monitor Turning Off

Check the Monitor Connection

Start by verifying if there’s a connection problem between your monitor and computer. If the connecting cable is loose or damaged, your monitor will turn off when connected. Simply power off the system, inspect the video cable and ports, and ensure everything is secure. Additionally, disconnect any external devices from your computer as they might interfere with the system.

Run Hardware and Devices Troubleshooter

Perhaps the monitor keeps turning off due to a minor hardware issue. Running Windows’ built-in troubleshooting software might help resolve some problems.

1. In Windows 10, press Win I to open Settings and navigate to Update & Security.
2. Under the Troubleshoot section, click Hardware and Devices and select Run the troubleshooter. Windows will scan for hardware changes. Follow the on-screen instructions to complete the process.

Disable Screen Saver

Windows has a built-in feature called screen saver that activates automatically if there’s no user activity for a certain period. This can make the monitor appear to enter sleep mode. Disabling this feature can solve the problem.

1. Type lock screen settings in Windows 10 and click the relevant result.
2. Click Screen saver settings and set it to None. Ensure the option – On resume, display logon screen – is unchecked.
3. Save the change by clicking OK.

Update Monitor Driver

If your monitor keeps turning off, consider updating the driver. To do this, go to Device Manager, right-click the display driver, and choose Update driver.

Follow the on-screen guidance to complete the process. Alternatively, you can use a professional driver update tool to handle this task.

Adjust Power Plan Settings

Power settings might be the main cause of the issue where the monitor keeps turning off. Often, the monitor turns off when plugged in. To prevent this, adjust the settings in Windows 10.

1. Press the Win X keys and select Power Options from the menu.
2. Click the link of Additional power settings to open a new window.
3. Click Change plan settings and set the On battery and Plugged in options to Never for both Turn off the display and Put the computer to sleep.

Increase System Unattended Sleep Timeout

If the above methods don’t work and your monitor continues to turn off, try setting System unattended sleep timeout to a longer duration. By default, it’s hidden, and you’ll need to make it visible by modifying the Windows Registry.

Note: Before proceeding, back up your registry items to prevent any mishaps. Follow the steps outlined in this post – How to Back up Individual Registry Keys in Windows 10.

1. Press Win R, type regedit, and click OK.
2. Navigate to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings and locate the specified directory, as shown in the image.
3. Double-click Attributes and set Value data to 2.

Next, increase System unattended sleep timeout.

1. Right-click the Windows icon and select Power Options, then click Additional power settings.
2. After clicking Change plan settings, choose Change advanced power settings.
3. Expand Sleep, click System unattended sleep timeout, and adjust it to a longer time, such as 30 minutes.

Note: The above tips apply when Windows is operational. If Windows 10 fails to boot, try these fixes in Safe Mode: check the connection, disable screen saver, adjust power settings, update the monitor driver, and set System unattended sleep timeout to a longer duration.
